Ascorn SKS

This is a simple cutscene format used by Ascorn in their game Patrician II. It is essentially Motion JPEG with frame index.

File header:

 4 bytes - "SK10"
 4 bytes - width
 4 bytes - height
 4 bytes - framerate
 4 bytes - number of frames
 12 bytes - unused?
 (4 bytes, 4 bytes) x N - frame index (first value - frame offset, second value - frame size)
 4 bytes - total size
 4 bytes - padding

Each frame is the standard JFIF data.
